Sealing Rust, Moss and Verdigris paints
It is possible to seal the paints by spraying matt varnish spray from a distance (up 1m away) so that it lands on a model almost dry. It is important not to wet the model and so only spray very light, fine coats. In this way the varnish should not dissolve the paint. This is not easy to do and so it’s very important to practice on spare models before trying to spray a nicely painted model.
Some varnish sprays change the colour of the rust, moss and verdigris paints and so it is essential to test the spray first.
Our customers have succeeded in sealing the paints using Rust-oleum, Crystal Clear Protective Coat spray and Vallejo matt varnish spray – please read more below:
Sealing effects paints – Example 1
A customer has sealed our rust effects paint using a spray varnish – Rust-oleum, Crystal Clear Protective Coat. We thought it a good idea to let our customers know about this.
Our customer would like to emphasise- slow and steady, sparing coats, with drying time.
Sealing effects paints – Example 2
Carlos tried Vallejo matt varnish spray to seal rust and moss paint. He stood 1 meter away from the model slowly spraying across it. Carlos sprayed a very light coat from above making sure the model got only very lightly “wet” – then waited 30 mins for it to dry and then tried a second coat doing the same thing.
In the end Carlos did a 3rd coat from 40-60cm away super light and fast and there was no reaction with the paints.

Also, an artist used Mylands Wax Polish (Toluene Free) to seal verdigris paint on a sculpture. He said that this was successful. I tried it myself and found that it changed the paint colour a little and made the finish slightly glossy, but it still looked good.
